Tonya is making a scale model of a monument that is 160 feet tall. If she uses a scale of 4 in. = 5 ft., how tall should she make her model?

It should be 128 inches or 10.67 feet tall

Step-by-step explanation:

Real size of the monument = 160 feet tall

Scale used by Tonya = 4 inches equal to 5 feet

Scale model of the monument = Real size of the monument / Scale used

Proportion between real monument and scale model = 160 / 5 = 32

It means that the proportion between the real monument and the scale model is 32

Scale model height = Proportion * scale used

Scale model height = 32 * 4

Scale model height = 128 inches

Scale model height = 128/12 = 10.67 feet (12 inches = 1 feet)
